Plugins are python files which are located either in this repository or as separate file somewhere externally.
Each plugin must define a class named Module that implements the abstract class cyberbot.api.Plugin.
Plugins are created for each room, meaning that each room that adds your plugin will load an own instance of your plugin's Init class.
When a plugin is activated in a room, code in cyberbot/room_plugin.py creates it once per room.
The API available to the room plugins is defined in cyberbot/api/room_plugin.py.
It allows plugins to have their own key-value store, send messages, react to room events etc.
Built-in modules are in cyberbot/modules/, a very simple example is echo.py.
